ASSEMBLING MACHINE.

Application filed October 30, 1922. Serial No. 597,878.

To all 10h 0m it may concern Be it known that I, Jonomit T. HoL'rFoTH, acitizen of the United States, residing at Highland Park, county ofWayne, State of lt tichigan, have invented Certain new and usefulImprovements in Assembling Machines, of which the following is aspecification.

This invention relates to improvements in assembling machines.

My improved assembling machine is especially designed by ine'forassembling the rims of spring cushions such as are shown in myapplication for Letters Patent, Ser. No. 558,733, filed May 5, 1922, andI have illustrated the same herein as embodied in such machines. Myimprovements are, however, desirable and readily adapted for theassembling of other parts, particularly those of a channel or similarcross section.

The main objects of the invention are:

First, to provide a machine 'oi' the class described which rapidly andeffectively joins or assembles parts oft: cross section, indenting theparts at the joint, thereby retaining them in assembled relation. 7

Second, to provide in a structure of the class described a machine whichis of large capacity and easily operated.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

l accomplish the objects of my invention by the devices and meansdescribed in the tollowing specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodinient of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisapplication, in which:

Fig. I is a fragmentary perspective view of a. machine for assemblingrims 0t cushion spring structures embodying my invention.

Fig. II is a fragmentary plan view, the lelithand end only of themachine being shown. it will be understood, howerer, that the righthandend is a duplicate of the lefthand except in the matter of the drive forthe shaft.

Fig. HT is a detail view partially in ver tical section on a linecorresponding to line 3-3 of Fig. II with thejaws open.

Fig. IV is a detail sectional view corresponding to that of Fig. IIIwith the jaws closed. a v

Fig. V is a detail perspective view of the jointbetwccn the assembledmember i In the drawing similar reference numerals refer to similarparts throughout the several views and the sectional views are takenlooking in the direction of the little arrows at the ends of the sectionlines; h p

' Referring to the drawing, I provide a frame comprising the endpedestals 1, longitudinal bars 2 mounted on the pedestals, and the tierod 3. As the mechanisms are in duplicate, that is, there are two setsof mech anisms, I will, for convenience, describe only one of them.These mechanisms are carried by beds 4 mounted upon the frame adjacenteach end thereof. The parts to be assen'ibl'ed are indicated at 5 and 6and are of U shape and S cross section, the endsbeing. connected by atelescoped joint,see Fig. V.

The bed member 4 is provided with an adjustable rest 7 for the piece ofwork 5, this rest being supported by the longitudinally slotted bar 8which is secured in its adjusted positions by the screw 9. Opposed tothis rest or thrust member 7 is a slide 10 hooked at 11 to receive thepiece of work 6. A positioning stop 12 is disposed at the side of thisslide. This slide is adjustably connected to a link 13, the link havinga series at holes 14: therein to receive the screws or bolts 15. Thepurpose of adjustment of the slide and of the rest 7 being to adjust themachine for the assembling'of rims of different sizes. a

The link 13 is connected to a'lever 16 pivoted at 17 to be acted upon bythe cam 18 on theshatt 19. The shaft 191's driven from the pulley 20which is connected to the shaft by a clutch 21, shown conventionally.The trip or clutch lever 22 is connected to the foot lever 23 so thatthe operator releases the clutch after the work has been placed. Thespring 24 returns the clutch control lever to its operative position sothat unless the foot lever 23 is held down the clutch is thrown -out atthe completion of each revolution of j the shaft. A positioning member25 is provided for the end of the piece of work 5, and a correspondingpositioning member 26 is provided for the end oi the piece of work 6,the purpose being to position the work so that the ends of the workpieces are supported in overlapping relation. The positioning member 26is yieldingly supported by the spring 27 so that it yields when theoverlapping ends are moved to engaging position, as shown in Fig. IV.

A jaw 28 is mounted upon the bed in relatively fixed relation to thepivoted jaw 29, which is pivoted at 30 and is acted upon by the cam 31on the shaft 19, so that the pivoted jaw carries the end of the piece ofwork 6 into engagement with the end of the piece of work 5,see Figs. IIIand IV. The spring 32 retracts the jaw 29. The cam 31 is timed relativeto the cam 18 so that the jaws are first actuated to engage the ends andthe slide 10 is then actuated to telescope the ends together. To insurethe retaining of the parts in telescoping engagement I provide anindenting tool 33, which is pivoted at 34:,and has blades 35 adapted toact while the telescoped parts are supported by the jaws. The tool isactuated by the cam 86 on the shai'twhich is properly timed so that theparts are first brought into. engagement by the lateral movementthereof, are then telescoped witl a longitudinal movement, and thenindented. By the aid of my machine the parts may be very rapidlyassembled and are very secure.

I have not attempted to illustrate or de scribe my improvements inembodiments or adaptations for assembling parts of other cross sectionsuch, for instance, as the plain channel or the like, as I believe thedisclosure made will enable those skilled in the art to which myinvention relates to em body or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
